Question about RAM and block data

[Nada Lachtar]

Hello,

 

I’m trying to trace the physical address in the RAM for some data that is being written to a block device. I have access to the QEMUIOVector buffer that hold that data. However, I’m not sure how to trace how’s it being written from the RAM to the buffer, and how to get the physical address for the data in the RAM if possible?

 

I hope you can help me with this,

 

Thank you,
